just wondering if any one out there in the UK have come across this before ...last October i was invited to take part in a tractor run in aid of bloke that has had the big c ...he collects for a charity for cancer and has had other fund raising events with old cars and bus's and had no worries ..but this was cancelled at the last hour because some one in formed the hosting group that it was illegal to have such a event ...reasons being a they weren't a registered charity but it goes to registered charity ..and that most of the tractors were old working farm tractors so the insurance would not cover us for such events .we had to be on white diesel and could not be in no more then groups of 6 and had to set off 10min apart ...there was over 60 of us going ...!!!..so any help on this would be greatly appreciated
